Zero Spangle Gi Sheet

Zero Spangle Gi Sheet is a galvanized steel sheet product with excellent performance and wide application. It is hot-dip galvanized steel sheet, also called spangle-free galvanized steel sheet. The substrate is a cold-rolled sheet. It has many advantages such as rust prevention, easy inspection, and longer service life. By reducing the lead content in zinc ingots and zinc liquid to dozens of ppm, Wanzhi Steel can produce products with no or very little spangle. We specialize in the production of spangle-free galvanized sheets with a width of 600-2000mm and zinc content of 40-275g/m2, and we provide multiple grades, such as DX51D+Z, DX52D+Z, DX53D+Z, DX54D+Z, DX56D+Z, etc.

If the size you need is not available, our technical engineers will customize the solution for you.

We can also provide slitting and customization services. Welcome to contact us online.

Hot-dip galvanized steel sheets Types

Hot-dip galvanized  steel sheets (often referred to as galvanized iron (GI)) are widely used in various fields of industry such as building construction, civil engineering, home appliances, office automation facilities, and automobiles.

They are divided roughly into two types according to surface appearance: regular spangle GI (see Fig. in which zinc crystals present in floral patterns (spangles); and zero spangles or minimized spangle GI.

American ASTM A653 Standard Galvanized Steel Sheet

• Commercial Steel (CS Types A, B, and C)

Commercial Steel is a low-carbon cold-formed steel, such as galvanized steel roof forming

• Forming Steel (FS Types A and B)

Requires higher draw ability than Commercial Steel, such as for lamp cover forming

• Deep Drawing Steel (DDS)
• Extra Deep Drawing Steel (EDDS)
• Structural Steel (SS) – (33,37,40,50,80)
• High Strength Low Alloy Steel (HSLAS)

European EN 10346 Standard Galvanized Steel Coil

Low carbon steel for cold forming (DX51D – DX54D)

• DX51D is equivalent to Commercial Steel, curved and profiled
• DX52D is equivalent to Forming Steel
• DX53D is equivalent to Deep Drawing Steel
• DX54D is equivalent to Extra Deep Drawing Steel

Structural Steels (S220GD – S350GD)

S220GD,S250GD,S280GD,S320GD,S350GD

Use structural steel for high load-bearing capacity, with a yield strength of 220-350

What is a hot dipped galvanized sheet?

Hot-dip galvanized steel sheets are made by repeatedly dipping the steel sheets into molten zinc to form a protective zinc layer on the surface of the steel sheets. This layer of zinc can isolate the external environment and serve as an effective barrier to extend the life of the steel sheets. It has a better effect than electro galvanizing.

Features

• No spangles: The surface of the zero spangles galvanized steel plate is smooth, with minimal or no spangles, which makes it more beautiful and suitable for occasions with high surface quality requirements.
• Corrosion resistance: The galvanized layer can effectively protect the steel plate from corrosion and extend its service life.
• Good processing performance: The zinc-free galvanized steel plate has good weldability, plasticity, and processability, and is convenient for stamping, bending, cutting, and other processing operations.
• Diversified specifications: Steel plates of different thicknesses, widths, and lengths can be provided according to customer needs to meet the needs of different application scenarios.

Learn about anti-fingerprint treatment

It is undesirable to leave obvious fingerprints on a clean and neat galvanized sheet, which is why anti-fingerprint treatment is necessary. This treatment will minimize the appearance of fingerprints and smudges, making the surface of the galvanized sheet look smooth and professional. For example, this treatment is used in building exterior walls or household appliances that require high aesthetics.

Skin Pass Treatment

Skin Pass Treatment involves passing the galvanized steel coil through a series of rollers to improve its flatness and surface quality. This treatment helps improve the appearance of the steel and provides a more uniform texture. It also reduces the risk of surface defects such as waviness or excessive roughness.

Oil treatment

The oiled finish is a protective coating that is rolled or sprayed onto the non-flake galvanized steel coils, and the oil is evenly distributed and left to dry, forming a protective film to prevent corrosion and maintain its appearance during storage and transportation. The oil acts as a moisture barrier to prevent the steel from coming into direct contact with air and moisture, thus preventing rust. It also minimizes the risk of scratches or wear on the surface of the steel plate, ensuring its beauty.

Dry Finish

As an alternative to the traditional oiling process, a different coating technique is employed, such as using an anti-fingerprint coating or a skin pass process. This treatment is achieved by eliminating the use of oil during the galvanizing process and helps to maintain the integrity of the galvanizing, thus producing a dry surface free of fingerprints and stains.

Chromate coating

Chromate is a compound containing chromium. Applied by spray, dip or roller, this coating acts as a barrier against moisture and other corrosive elements, which can extend the life of the steel and reduce the need for frequent maintenance. Chromate coatings also enhance the adhesion of paint or other coatings on the steel surface. This makes them suitable for applications that require further treatment or customization of the steel. Another advantage of chromate coatings is versatility. They can be applied to automobiles and electrical equipment, among other applications.

Application

• Decoration and protection of building exterior walls, roofs, partitions, and other parts.
• Making the shell and internal components of household appliances such as refrigerators and washing machines.
• Parts such as the body, exhaust system, and chassis components improve the corrosion resistance and service life of vehicles.
• Electrical housings, cable trays, switch cabinets, and other components to prevent corrosion caused by moisture and improve the service life and reliability of equipment.
• Furniture manufacturing, packaging industry, machinery manufacturing, and other fields.
